Help with Trimming Learjet 35!

I’’ve read posts. I’ve watched tutorials. But no matter what I do, I cannot bind the Learjet 35 pitch trimming functions to my joystick (Thrustmaster T1600/TWCS).

The tutorials say that the Pitch trim barrel switch on the left side of the yoke should be bound to INCREASE AP PITCH HOLD REFERENCE and DECREASE AP PITCH HOLD REFERENCE. So I bind the two buttons that I normally use for trimming up/down on every other aircraft to those commands. It does nothing. (I understand that AP has to be off.) Then the tutorials say the barrel switch only works if the center button is depressed. But I have yet to find a function in the default controls menu that activates that center button. I see instructions about The Smoke On/Smoke Off, and Tailhook commands but they only affect the nose steering/AP on-off when I bind them. Nothing activates/depresses that little center button on the barrel switch. So as much as I love this jet, I cannot trim it. I can manually control the barrel switch with the mouse (and even then when I press the center button it does not show it depressing). Surely I am missing something…? Trimming is a basic function and should not require multiple switches, correct?

On my TM Boeing TCA yoke I have the following bindings, which work in both the 2020 and 24 35A:

ELEVATOR TRIM DOWN (NOSE DOWN)

ELEVATOR TRIM UP (NOSE UP)

Hope this helps!

Yes, those are the commands I normally bind on all other aircraft for trimming purposes. As I said in my post, when I do that, my buttons do not move the barrel switch to the Nose Up or Nose Down position to trim the aircraft. The other issue (as I posted) is that Flysimware tutorials mention that the barrel switch won’t do anything unless you hold the “center button” in. So I have yet to find a way to assign anything in the Controls bindings to do that. Are you saying that, on your yoke, just binding buttons to ELEVATOR TRIM DOWN (NOSE DOWN) / ELEVATOR TRIM UP (NOSE UP) enable you to trim the Learjet, and you see the barrel switch visibly reacting?

When hand flying, I am able to trim the Learjet with those bindings. There is no visible effect on the barrel switch that I can see. This is not a concern for me as I fly with the yoke hidden at all times.

I guess I will try again. I too am not concerned with visible resaction as I hide the yoke also. It seems when I tried that “normal” binding the Learjet did not react like it was being trimmed. Thanks.

Your advice worked! The tutorials on YouTube and documentation make it sound so complicated, and I know there are other functions and yoke buttons that are more complex but I like simplicity. The thing that really threw me was the fact that there was no visual indication of those trim up and trim down controls working. Have flown other aircraft where you could see a trim wheel or an indication on the MFD of trim status, not having any requires getting used to . Now I am watching some tutorials on using auto pilot which is a bit different from other Jets I have flown.

Glad to hear! Have fun flying the Lear!

Actually, now that I’ve got the bindings to work and have familiarized myself with the Learjet’s different form of VNAV, etc. I love it! It’s a great aircraft, capable of high speeds an spot-on ILS approaches as well as great hand flying as it flies really well and (as far as a non-real-world pilot can say) very accurately.

I still haven’t found a binding that works for Taxi Lights, Landing Lights, and the altitude bug. My old ones do nothing. But I’ll keep trying and even without those I am having fun flying this baby.

Just landed after my 2nd flight of the day in the 35A, and yes it’s a rock solid flyer! I never had the opportunity to fly/ride in a Learjet, but from an IRL GA pilot perspective, it is wonderful to hand fly. After a week of airliners last week, was a real delight to step away from an FMC/FMS and just go with SimBrief and a GTN750/650. As for those external lights bindings, nada for me too LOL. Cheers!

This was a fun plane to get set up in SPAD.next.

Unsure if these are bindable in the Sim, but landing/taxi lights below. In brief, 2 is off, 1 is taxi, 0 is landing (it’s one switch per side, three positions).

The altitude bug is the “ALERTER_DIGITAL” LVAR.

The Autopilot is easily the most difficult one I’ve done in SPAD, and it’s still not working exactly as it should.

I’d recommend joining FSW’s discord; they have a channel dedicated to Control Bindings. :slight_smile:

I can’t get the trim on my lear 35 to work at all. MSFS 24. HONEYCOMB 1st gen bravo yoke and throttle. Please HELP

I have the honey comb 1st gen brave throttle and yoke. Using these same settings I can’t get from to work at all. Please help.

Hello again, I’m not a honeycomb owner so perhaps we might ask @SteveKane to help? For that to work, you might want to restate exactly what is not working for you now, so it is very clear what the control binding issue is. Also, are you flying the 35A in 2020 or 2024? I no longer fly in 2020 and only fly the new 24 version of the 35A, so perhaps also state what version you are on for clarity?

I’m in 2024. At first I had it set to just the nose down and nose up. Then I read some articles and it indicated to try it to switch to the 100 to 100 axis and still no joy

I’m at work currently, but I’ll try to take a look tonight to see if I mapped anything custom on the Learjet for the pitch trim controls.

Ok. Thanks :+1:

I’m even okay with doing a remote into my computer to help look over my stuff that makes it easy

Okay, I have the Boeing TM Yoke, but the hardware is irrelevant, as it’s just a momentary switch that’s being used.

That said, there’s nothing special: I use the in-sim ELEVATOR TRIM UP (NOSE UP) and the ELEVATOR TRIM DOWN (NOSE DOWN) settings in FS2024, bound to the “X” switch on my yoke (left thumb switch). I don’t recall any planes, Asobo or 3rd party, that use anything other than this setting for pitch trim.

If that’s not working, then there’ something else going on, maybe your hardware? But if this works on other planes, then there’s something else in play.

Now if you’re talking Pitch Reference, which is how you adjust the climb or descent pitch angle, then I have the Y switch to the left of my pitch trim knob set to DECREASE AP PITCH HOLD REFERENCE and INCREASE AP PITCH HOLD REFERENCE. (I actually have this mapped in SPAD.Next, but I’m 90% sure this’ll work identically if setting it in-sim. )

Hope this helps.
